I'll fuck you standing, show me what's under your skirt

A man stands beside a woman leaning over a bed frame, lifting her skirt to reveal her underwear. He pulls her panties aside and penetrates her from behind while she kneels. She then performs oral sex on him before he resumes fucking her doggy style, gripping her hips tightly as he thrusts. The final shot is a close-up of his cock entering her from behind.
